Crossandra Plant Care

Brilliant clusters of apricot-colored flowers give firecracker flower (Crossandra infundibuliformis) its descriptive common name. The tropical evergreen grows outdoors in U.S. Department of Agriculture plant hardiness zones 10 and 11, but it's usually enjoyed as an indoor potted plant. Outdoor-grown firecracker flowers can grow up to 3 feet tall, but potted plants tend to reach only a 12-inch height. Planting it in pots outdoors can brighten up the garden while still allowing you to bring the plant indoors if a frost threatens.

1

Grow firecracker flower in a pot filled with moist potting soil that's rich in organic matter and holds moisture well. Use a pot with bottom drainage holes so excess moisture doesn't collect in the bottom of the pot and cause root rot.

2

Set the plant in an indoor area that receives direct sunlight for at least six hours daily. Place outdoor plants in a location with bright morning sun and light afternoon shade.

3

Water firecracker flower when the soil surface in the pot feels dry. The soil should otherwise remain moist, but not waterlogged, at all times. Empty any water that collects in the drip tray promptly after watering.

4

Dilute a soluble tropical houseplant fertilizer in water according to the directions on the fertilizer package. Fertilize the plant with the solution once a month from spring to fall, when the plant is actively growing.

5

Snip off the flower stalks at their base after the blossoms wilt and die. Firecracker plants flower year-round, so prompt flower removal improves the appearance of the plant.

6

Repot the plant into a container one size larger every two to three years, or when the roots become crowded and begin growing from the bottom of the pot. Plant the firecracker flower in the new pot at the same depth it was in its old pot.

Tip

If you grow firecracker plants outdoors in a warm climate that doesn't experience frost, mulch around the base of the plants to retain moisture and protect the roots from any unexpected cold winter weather. Garden-grown plants may require more frequent watering to keep the soil moist.
